You've outgrown the little 10 W trickle panel. You need actual charging current for a 12 V system — maybe the caravan fridge, a small pump, or keeping a workbench battery bank healthy between sessions.
This JAYCAR 40 W monocrystalline panel gives you four times the output of the entry unit in the same family. Monocrystalline cells mean better efficiency per square inch, so you get more watts from the same roof space or tray lid.
Pair it with a suitable charge controller and you've got a proper 12 V charging setup that doesn't rely on grid power.
